We want to test the effect of the "maybe later" functionality that was designed last year. The control banner is the **(control|variant) banner** of **desktop-de-05**.
**Acceptance Criteria**
* Both banners show the progress bar.
* The design of the variant banner is implemented as shown in the [design file](https://www.figma.com/file/9O4yGHYVoB69p3l81MBxVt/Banners-2021?node-id=650%3A14013).
* In smaller viewports, the "Vielleicht später" element is shown in the bottom right corner of the banner.
* Clicking on the "Vielleicht später" element
* collapses the banner to what's called the [small version](https://www.figma.com/file/9O4yGHYVoB69p3l81MBxVt/Banners-2021?node-id=659%3A22803).
* is logged using the schema WMDEBannerSizeIssue and passing the viewport dimensions.
* initially shows the collapsed banner on the next page/banner load.
* Clicking on "Jetzt unterstützen" in the small version
* expands the banner again.
* logs the banner expansion using the schema WMDEBannerSizeIssue and passing the viewport dimensions.
* initially shows the collapsed banner on the next page/banner load.
* Clicking on the grey X icon closes the banner completely and prevents banner display for the usual amount of time.
